There's a fun new app available: the LoveCrochet app. You can easily download patterns and make a library to organise them. The app also has a row counter and every week new and free patterns will be released. It's also possible to connect your Ravelry-account to the app, so you have all your patterns stored on your device. You can find the app in Itunes if you search for LoveCrochet. More information about the app is available here.
